摘要
图像置乱技术可以做为图像信息的一种加密算法,其中Arnold变换被广泛应用到图像置乱算法中。由于Arnold变换只能直接应用到正方形图像中,本文结合Arnold变换和混沌Logistic映射,提出了一种针对非正方形数字图像置乱的算法。通过对算法进行安全性能的讨论,证明该方法具有较好的实用性。
Image scrambling technique can be viewed as an encryption algorithm for the image information, and Arnold transformation is applied widely for the image scrambling. Because Arnold transformation is only applied for square images directly, combining Arnold transformation and Logistic map, we proposed a new scrambling algorithm for non-square digital images. Additionally, the practicality is proven by secure analysis.
